SHUTTLE LOOKING AND RELEASING CONTROL.

Application filed February 1, 1927, Serial No. 165,060, and in France February 25, 1926.

The invention relates to devices for locking and releasing the shuttle in looms and bers the positionof one of the shuttle releasing lever, the other arm has for its object an improved control for these devices which presents, in comparison with the motions employed heretofore, the advantage of permitting an absolutely accurate adjustment of the locking and releasing points of the shuttle to be obtained.

This improved control, which is constructed with a view to permitting the.locking and releasing points to be advanced or retarded and an accurate adjustment to be obtained, is characterized by the feature that the shuttle releasing lever is actuated from the rod of the batten through the medium ofacombination of transmission memwhich is adjustable relatively to another, for example a bent lever pivotally mounted upon the said rod, one of the arms of which lever actuates being pivotally mounted on the end of a rod the other end of which is adjustably mounted in acap pivotally'mounted upon a trunnion integral or virtually integral with the frame of the. loom. I

A form of such an improved control is described hereinafter and illustrated diain a cap 17 pivoted on the trunnion 18 lntegrammatically by way of example in the accompanyin drawing;

In this rawing, 1 is a legof the batten, 2 the rod actuating the batten, 3 the shuttle locking tongue comprisin at its end a rod' 4. The shuttle releasing ver is formed as a bell crank lever 5-6 pivotally mounted at 7 upon the pivot of the rod 2. The function of the arma5 is to pull back the rod 4 of the tongue 3 in order to release the shuttle. The second'arm 6 of the said lever is formed with a slot 8 in which is adapted to slide freely a trunnion 9 carried by the arm 10' of a bell crank lever which is pivoted at 11 upon the rod 2. The other arm 12 of said bell crank lever is pivotally. mounted at 13 upon the end of a rod 14 mounted at its otherend in an adjustable manner, by means of a nut 15 and counter nut 16. for example,

gral or virtually integral with the frame of the loom. 19 is the shuttle locking spring.

It will be understood that the reciproeating motion of the rod 2 and consequently of the point of pivotal mounting 11 of the bent lever 10-12 causes the locklng and releasing of the shuttle by actuating the lever control for looms,

-bers comprisin 6-5. It will also be understood that it is possible to adjust with as much preeisiom as desired the lock and releasepoints by adjusting thelength of the rod 14.

Naturally, it is Possible, without going outside the scope o the invention, to make modifications and improvements in details, and equivalent means may be employed.

What I claimis:

1. An improved shuttle lock and release control for looms, with adjustment of the lock and release points comprising a batten a batten rod, a shuttle releasing lever an acombination of transmission members adapted to actuate said shuttle releasing lever bysaid batten rod the arrangement being such that the, position of one of said bers comprisin a two-armed bent lever pivotally mounte on said batten rod and a second rod adjustably and-pivotally mounted at one endon the loom frame and pivotally connected at the other end to one end of said bent lever the other end of said bentlever being adapted to actuate said shuttle releasing lever. v.

- 2. An improved shuttle lock and release with, adjustment of the lock and release points comprising a batten a batten rod, a shuttle releasing lever an a combination, of transmission members transmission members is adjustable relatively to the other, the transmission ,mem-

adapted to actuate said shuttle 'releasing' lever by said batten rod, the arrangement 1 being such that the position of-one'of said transmission members is adjustable relatively to the other, the transmission mema two-armed bent lever pivotally mounte on said batten-rod, a trunnion on the loom frame, a cap pivotally mounted on said trunnion and a second rod adjustably mounted in said cap, one arm of said bent lever being adapted to actuate said shuttle releasin lever and the other arm of said bent lever ing pivotally mounted en the end of said second rod.

3. An improved shuttle lock and release control comprising a shuttle locking tongue and a rod on the end of said tongue, a shuttle releasing levercomprising a be crank lever pivotally mounted on the-batten rod, one arm of said lever being adapted to act upon said tongue rod and the other arm having-in it a slot, a two-armed bent lever pivota y mounted on said batten rod, a no trunnion on one arm of said bent lever, said trunnion moving in the slot on said bell crank lever and thereby providin a pivotal mounting for said arm, a second trunnion on the loom frame, a cap pivotally mounted on said trunnion, a second rod adjustably mounted at one end in said cap and at'the other end pivotally connected to the other arm of said bent lever, the arrangement being such that the movement of thebatten rod produces the locking and releasing of the shuttle through the bell crank lever and that the moments of locking and release can be varied by adjusting the length ofsaid second rod. a

In witness whereof, I hereunto subscribe my signature.
